first robot

Just got this finished tonight, with some help on the code from experts on the forum here.

The chassis is half of a case form a broken power inverter and the battery is a 11.1 volt 1.5 AH lipo.

Cool, so what does do?

Right now, it follows light. I have an ultrasonic rangefinder on the way to add object avoidance, which will help. Currently, it mostly just drives around and crashes into stuff.

Which arduino did you use?
How long did it take to build it?
